The NLM and DIALOG user will normally make the cost-effective choice by printing online at 1200 baud rather than offline. At 300 baud the offline print remains the economical choice. Given the most reasonable estimates of citation length, offline printing is now the choice in all cases for the BRS user of MEDLINE. The cost estimates are based on the application of the Boyce-Gillen formula. Page charges are converted to citation charges where necessary.
